3/4in Support Bearing

The 3/4in Support Bearing from Flaming River is a critical component for high-performance steering and suspension systems, especially in custom hot rods, race vehicles, and heavily modified trucks. This support bearing handles lateral and axial loads that develop during aggressive cornering, acceleration, and braking—situations where factory steering columns simply cannot survive. Whether you're building a street machine with modern rack-and-pinion geometry or upgrading a classic vehicle's steering backbone, this bearing isolates vibration and prevents column flex that degrades handling precision and driver feedback.

Engineered by Flaming River, a leader in custom steering solutions, the 3/4in support bearing uses precision ball-race construction to distribute loads evenly across its bore and outer race. The 3/4-inch bore diameter accommodates most aftermarket steering columns and shaft assemblies, while the bearing's sealed design resists contamination from road salt, moisture, and engine bay heat. Proper support bearing installation reduces unwanted column movement, eliminating steering slop that commonly appears in vehicles with worn or inadequate stock bearings. The compact footprint (4 x 1 x 7 inches) and lightweight build (0.72 lbs) make integration straightforward during custom fabrication or restoration work.

This bearing is ideal for mechanics and builders upgrading vintage vehicles to modern handling standards, as well as those installing independent front suspension systems or custom rack conversions. Installation typically requires mounting the bearing at the firewall or column brace point, where it prevents excessive play while allowing the column to collapse safely in a crash. Verify your steering column shaft diameter and mounting environment before ordering; this 3/4in size works across most popular custom steering kits, but confirmation of fit ensures a first-time installation.
